DETAILED DESCRIPTION OF EMBODIMENTS OF THE DISCLOSURE

Embodiments of the present relate generally to structures that are configured to operatively join straps or similar structures such as ropes, cords, webbing or the like (collectively “straps”). In particular, a linkable strap-retaining connector is configured to be linked to one or more complementary linkable strap-retaining strap connectors to establish an adjoined strap linking system that operatively connects multiple straps or similar structures at a common location. In at least one embodiment, in a linked state, the adjoined strap-retaining connectors may operate as a sternum connection for a backpack or the like engaging straps from different sides.

The strap-retaining connector provides a linkable connector element including a strap adjuster and attachment couplers that can be mated in adjoining relation to one another such that the strap-retaining connector may be coupled to one or more other strap-retaining connectors via complementary attachment couplers. Thus, multiple strap-retaining connectors may be attached to different straps and joined together at a common location while still permitting operative length adjustment of the straps. The mating attachment between the strap-retaining connectors may be easily reversed to facilitate repetitive connection and disconnection by a user as desired.

FIG. 4 illustrates a simplified end view of the second attachment coupler 138, according to an embodiment of the present disclosure. The outer panel 146 laterally extends from the main body 124 via the extension beam 148. The first channel 150 is above the extension beam 148 between the outer panel 146 and the inner surface 152 of the main body 124, and the second channel 151 is below the extension beam 148 between the outer panel 146 and the inner surface 152 of the main body 124.

FIG. 5 illustrates a perspective view of a strap linking system 200 including a first strap-retaining connector 100 a removably coupled to a second strap-retaining connector 100 b, according to an embodiment of the present disclosure. The first strap-retaining connector 100 a and the second strap-retaining connector 100 b may be sized and shaped the same. For example, each of the first strap-retaining connector 100 a and the second strap-retaining connector 100 b may be sized, shaped, and configured as shown and described with respect to FIGS. 1-4.

Referring to FIGS. 1-5, in order to couple the first strap-retaining connector 100 a to the second strap-retaining connector 100 b, the first attachment coupler 136 of the second strap-retaining connector 100 b is axially aligned with the second attachment coupler 138 of the first strap-retaining connector 100 a. In particular, an end 173 of the second attachment coupler 138 of the first strap-retaining connector 100 a is aligned with the open end 160 of the first attachment coupler 136 of the second strap-retaining connector 100 b. The outer panel 146 of the second attachment coupler 138 is inserted into the open end 160 of the coupling groove 140, the second strap-retaining connector 100 b is slid in relation to the first strap-retaining connector 100 a in the direction of arrow A. In this manner, the first strap-retaining connector 100 a slidably couples to the second strap-retaining connector 100 b. With continued urging in the direction of arrow A, the locking protuberances 172 (and the locking protuberances 164 and 166) may resiliently deflect into a secure locking relationship, so as to snapably secure the first attachment coupler 136 to the second attachment coupler 138. Optionally, the first strap-retaining connector 100 a and the second strap-retaining connector 100 b may not include one or more of the locking protuberances 164, 166, and/or 172.

In order to disconnect the first strap-retaining connector 100 a from the second strap-retaining connector 100 b, the first strap-retaining connector 100 a is slid relative to the second strap-retaining connector 100 b in an opposite direction from arrow A. For example, an individual may slide the first strap-retaining connector 100 a and the second strap-retaining connector 100 b relative to one another, such as in the direction of arrow A′, providing sufficient force to deflect the locking protuberances 164, 166 and/or 172 into a disengaged position so as to unlock and uncouple the first and second strap-retaining connectors 100 a and 100 b from one another.

The strap linking system 200 may include additional strap-retaining connectors 100. For example, a third strap-retaining connector (not shown) may couple to the first attachment coupler 136 of the first strap-retaining connector 100 a, and/or a fourth strap-retaining connector (not shown) may couple to the second attachment coupler 138 of the second strap-retaining connector 100 b, such as described above. Additional strap-retaining connectors 100 may also couple to the third and fourth strap-retaining connectors, and so on.

FIG. 6 illustrates a perspective front view of the strap linking system 200 having the first strap-retaining connector 100 a that retains a portion of a first strap 300 uncoupled from the second strap-retaining connector 100 b that retains a portion of a second strap 302, according to an embodiment of the present disclosure. FIG. 7 illustrates a perspective front view of the strap linking system 200 having the first strap-retaining connector 100 a that retains the portion of the first strap 300 coupled to the second strap-retaining connector 100 b that retains the portion of the second strap 302. Referring to FIGS. 1-7, the strap-retaining ends 104 of the first strap-retaining connector 100 a and the second strap-retaining connector 100 b adjustably retain the portions of the first strap 300 and the second strap 302, respectively. The connector coupling portions 106 of the strap-retaining connectors 100 a and 100 b may be removably coupled to one another, as described above. When the connector coupling portions 106 of the strap retaining connectors 100 a and 100 b are coupled together, as shown in FIG. 7, the strap linking system 200 links or otherwise couples the first strap 300 to the second strap 302, such as proximate to a sternum of an individual.
